Hey my pc is a MSI X2B I got it recently, and this problem is starting to annoy me. When I turn the pc off (completely) the internet blinking light coming from the back of the pc is still blinking every once in a while. Not only is it weird but annoying because its actually a pretty powerful led that light up my whole wall. The led blinking is coming from where you plug in the internet LAN cable. And if i unplug the cable the blinking stops..
